  • Patent number: 9587449
    Abstract: Example workover vehicles for removing and installing sucker rods and tubing of completed wells include a mast having a distinctive spatial relationship with various equipment of the vehicle. The mast has a series of vertical corner posts or weight bearing derrick legs that define the mast's horizontal footprint. In some examples, a tubing storage rack is situated mostly within the footprint while a rod storage rack is mostly beyond the footprint. A robot traveling vertically along the mast transfers rods and tubing between the well and the appropriate storage rack. In some examples, the rod storage rack pivots between an extended operative position and a retracted transport position. In some examples, a robotic jib transfers rods or tubing to and from a lay-down storage area. Some example robot jibs are movable to a fully deployed position for normal operation and a stored position within the mast's footprint for vehicle transport.

  • Patent number: 9574417
    Abstract: A bottom hole assembly for engaging and removing an object within a wellbore comprises a cutting tool at a lower end. Continued engagement of the cutting tool with the object is facilitated by an axial compression device disposed within the bottom hole assembly below the anchor of the bottom hole assembly. The axial compression device comprises a compressed position and an expanded or extended position. As the object is being cut or abraded, the axial compression device moves from the compressed position toward the expanded position so that a continued downward force is transferred to the object by the bottom hole assembly.

  • Patent number: 9534463
    Abstract: A pump down tool includes a resilient cup on the tool exterior to minimize leakage of pumped fluid around the outside of the tool when the tool is pumped into a well. The resilient cup is concave toward an upper end of the tool so it expands upon application of pressure to pump the tool into the well. The resilient cup is capable of expanding to a diameter sealing against the inside of the casing string. A fluid bypass around the resilient cup allows a fraction of the pumped fluid to stir up any proppant lying in the path of the tool thereby allowing the tool to move through a horizontal well without having to plow through the proppant.

  • Patent number: 9534446
    Abstract: A method of drilling a subterranean well from a surface location. The method comprises estimating a target formation depth, estimating a target formation dip angle and calculating a target line that creates a top and bottom of the target formation that forms a first projection window. The method further includes drilling within the first projection window, transmitting information from the subterranean well and projecting a target deviation window. The method can further comprise ceasing the drilling of the well and performing a well survey so that well survey information is generated. The method can then include estimating a formation dip angle with the well survey information and rig surface equipment monitoring data, calculating a target line that creates a revised top and bottom of the target formation that forms a second projection window, and drilling within the second projection window.

  • Patent number: 9534470
    Abstract: The invention relates to a method and apparatus for of controlling the flow of a fluid. The fluid comprises a liquid phase and a dissolved gas phase. The fluid passes through a valve, the valve comprising a fluid inlet and a movable body located in a flow path through the valve, the movable body being arranged to move freely relative to the opening of the inlet to vary the flow-through area through which the fluid flows by means of the Bernoulli effect. The dimensions of the valve are such that flow of the fluid past the movable body causes a drop in pressure to below the bubble point of the gas phase in the liquid phase, thereby increasing flow of the fluid through the valve.
